Abstract

The invention relates to a method for acquiring a code scanning image, which comprises the following steps: after code scanning equipment is fixedly installed, obtaining a parameter adjusting curve of the code scanning equipment according to the distance between the code scanning equipment and an object to be scanned, an environment illumination value and code scanning parameters of the code scanning equipment, the code scanning parameters comprising an exposure value and a focal length value; determining a parameter adjustment scheme of the code scanning equipment by using the parameter adjustment curve; and adjusting the equipment parameters of the code scanning equipment according to the parameter adjustment scheme, and obtaining a code scanning image. According to the method and the device, in the application of some industrial environments, the parameter adjustment of the code scanning equipment is reduced, and the code scanning speed is increased on the premise that the code scanning error rate is not increased. The invention further relates to a device for acquiring the code scanning image and code scanning equipment.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method, a device and a code scanning device for acquiring a code scanning image. Background technique [0002] With the development of science and technology and the continuous improvement of the level of informatization in society, the application of barcodes and two-dimensional codes has become more and more extensive. Bar code and two-dimensional code technology has also begun to be accepted and used by major industries because of its accuracy and reliability, fast data input speed, low cost and large degree of freedom. However, the current application of barcodes and QR codes is becoming more and more complex. In some industrial applications, the scanning speed of the scanning equipment needs to be accelerated, and the error rate of scanning the code should also be reduced. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present...
